WiFi Temperature and Humidity Sensor
Model RTH-WD
In the WiFi sensor, a Swiss chip from Sensirion is used, with a temperature measurement range of -20 to +85 degrees Celsius, and the humidity measurement range of this sensor is 0 to 100 percent.
The actual temperature measurement accuracy is ±0.3 degrees Celsius and the humidity measurement accuracy is ±3 percent.
Modbus TCP
Support for Modbus TCP Protocol over WiFi
Temperature & Humidity Range
Temperature : -20 to +85 °C
Humidity : 0 to 100%
Input Voltage
Input Voltage: 220V
Relay Outputs
Two 1A Relay Outputs
Web Configuration
Equipped with a professional web service for configuration via browser
Ethernet network as WiFi under the Modbus TCP, JSON, and HTTP software protocol
The communication protocols embedded in this device provide the capability to connect to various PLCs, DCSs, and RTUs, and it can also communicate with various equipment that supports Modbus TCP, JSON, and HTTP.
The measurement accuracy of this sensor is suitable for server rooms, livestock and poultry farming centers, mushroom cultivation halls, greenhouses, and all warehousing and industrial environments, laboratories, cold storage facilities, office and residential buildings, etc.
Note
– Since this device has a series of thermostatic modes, in cases where temperature or humidity control is required, this sensor can be used.
– This sensor is specifically designed for displaying and monitoring temperature and humidity in industrial systems.
The relays in the WiFi sensor have three different control modes:
Mode 1: Under the Modbus network
Mode 2: Based on ambient temperature
Mode 3: Based on ambient humidity
Each relay has the capability to define a mode for it separately. For example, the settings of one relay can be configured based on temperature and the other based on the Modbus network.
When the relays are set based on ambient temperature and/or humidity, they operate in such a way that a range is defined for them: a temperature is received as the Max temperature, for example 25 degrees, and a temperature is received as the Min temperature, for example 23 degrees; based on this information, the temperature range of 23 to 25 degrees becomes the control range. Humidity can be configured in the same way.
Note: The difference between these two numbers cannot be less than 1 degree for the temperature mode and cannot be less than 5 percent for the humidity mode.
In thermostatic modes, there are two modes, decreasing and increasing, which we have explained in the relevant section.
If you want to use this sensor on the network (you define an IP for the device), by entering the IP, the web service opens and all settings can be performed through the web service. One of the applications of the web service is that, for example, if these sensors are used in an organization’s or a refinery’s internal Ethernet network, all settings can be defined remotely exactly through the network.
If in the environment where you are using this sensor there is a modem with a valid IP, by applying a series of network settings you will have the possibility to remotely connect to the web service of this device via the internet, view the temperature and humidity values, and apply any settings to the device.
